| Where there are Little Desert Pocket Mice, there is sand. They seem to need sandy soil. Many pocket mice and other heteromyid rodents do, although some thrive on rocky slopes or other substrate. Not much is known about this species. There is almost no information on reproduction, but in most small desert mammals, reproduction peaks following a rainy period, when plants spring up and food is abundant. These mammals forage at night, often under the shelter of desert shrubs, trying to avoid becoming food for owls. They escape the heat of the day, and daytime predators, by resting in their burrows.
Little Desert Pocket Mice have soft, almost silky fur, and no spines on their rumps. There are no known fossils.
